Abstract
The utility model discloses a motor provided with an inner circulating cooling system. The inner circulating cooling system comprises a stator, a fan disc and a blade cover. The fan disc is fixed at the rear end of a motor rotor shaft, the blade cover is fastened on the rear end face of the motor stator, the fan disc is provided with a plurality of blades and ventilating holes, the concave portion of the rear end face of the motor stator is provided with a plurality of deep venting holes leading to the inside of a motor stator iron core, and the fan disc, the ventilating holes, the deep venting holes and a ventilating window on the blade cover form the inner circulating cooling system of the motor. When the motor runs, the blades stir air to produce airflows, the airflows enter the concave portion of the end face of the stator through the ventilating holes among the blades, absorb heat produced by current, then return back to the fan disc and are discharged out through the ventilating window of the blade cover. The motor can discharge out heat produced by the current from the ventilating window of the blade cover and has good effect of reducing risen temperature really.
Description
Technical field
The utility model relates to field of motor manufacturing, especially refers to a kind of motor with interior circulating cooling system.
Background technology
Existing traditional motor all is provided with cooling fan in rearward end, and purpose is to the motor cooling, and the temperature rise of control motor prevents motor overheating and burns.But the fan of most common electric machines all is located at outside the casing, incites the wind cooling only for when fan rotates with the axis the tail end of motor, so the effect of cooling is unsatisfactory.The motor that has receives the ambient temperature effect of workplace, still is easy to heating.Too high and burn for fear of temperature rise, the cooling of having to sometimes midway shut down influences operate as normal.Therefore the motor type of cooling is improved, to prevent electric machine temperature rise too high be useful.
The utility model content
The purpose of the utility model is: to existing common electric machine only externally the tail end type of cooling of inciting the wind cooling improve, at motor internal circulating cooling system is set, thereby improves the cooling effect of motor, prolong the useful life of motor.
The technical scheme of the utility model technical solution problem is: the motor with interior circulating cooling system; Circulating cooling system comprises stator, fan disk and blade cover in said; Fan disk is fixed on the rear end of rotor axis of electric; Blade cover is fastened on the rear end face of motor stator; Said fan disk is provided with some fan blades and ventilation hole, is provided with the inner degree of depth air vent hole of some through motor stator cores at the recess of said motor stator rear end face, and the ventilating window on said fan disk, ventilation hole, degree of depth air vent hole and the blade cover constitutes circulating cooling system in the motor.
What the utility model was useful is: motor in the running; Fan disk is along with rotor rotates, and the air-flow that the fan blade agitation air on the fan disk produces is from the recess of the entering of the ventilation hole between fan blade motor stator end face; It is inner to get into electric machine iron core through degree of depth air vent hole again; Be back to fan disk again behind the heat that absorption current produces, discharge from the ventilating window of blade cover then, thereby reach purpose to the motor cooling.
Description of drawings
Fig. 1 is the released state schematic perspective view of the utility model;
Each division name is claimed and is numbered among the figure: 1-stator, 2-fan disk, 3-ventilation hole, 4-degree of depth air vent hole, 5-blade cover, 6-fan blade, 7-ventilating window.
Embodiment
As shown in Figure 1, the motor of circulating cooling system in the utlity model has is conventional motors to be depended merely on the type of cooling that fan incites the wind cooling to the outside tail end of motor improve.Circulating cooling system comprises stator 1, fan disk 2 and blade cover 5 in said; Fan disk 2 is fixed on the rear end of rotor axis of electric; Blade cover 5 is fastened on the rear end face of motor stator 1; Also be provided with some fan blades 6 on the fan disk 2; In the middle of per two fan blades of fan disk 26, be provided with ventilation holes 3, be provided with the degree of depth air vent hole 4 of some through motor stator 1 core interior at the recess of said motor stator 1 rear end face, the ventilating window 7 on said fan blade 6, ventilation hole 3, degree of depth air vent hole 4 and the blade cover 5 constitutes circulating cooling system in the motors.
Motor in the running, armature spindle drives fan and rotates simultaneously and produce air-flow.Owing to be provided with ventilation hole 3 and degree of depth air vent hole 4 with motor stator 1 rear end face on the fan disk 2; Motor stator 1 core interior so the air-flow that produces can go directly; Take through the heat that magnet exciting coil produces electric current out of with air-flow; And discharge from the ventilating window of blade cover 57, truly have effect preferably to reducing electric machine temperature rise.
